How Installing Energy-Efficient Windows in Kingstowne Saves You Money
Switching to energy-efficient windows can help improve the comfort of your home and help you save on electricity bills. Here are more details about how switching out your windows could benefit you:
- Save on electricity bills: Since energy-efficient windows decrease how much energy you need to heat or cool your home, the switch can help you save around $359 annually on your energy bills in Kingstowne.
- Protect your valuables: Many Energy Star certified windows have low-emissivity coatings, which not only provide better insulation for your home, but also filter out damaging UV rays, preventing your furniture, carpet and other valuables from fading.
- Decrease your carbon footprint: Since energy-efficient windows improve the insulation in your home, you can cut your carbon footprint by about 12%, according to Energy Star.
- Protect your investment: If you have a relatively old home, your windows are most likely in need of replacement. Upgrading your windows can improve the insulation in your home and also help raise the value of your house if you decide to sell.
Estimated Cost of Window Replacement in Kingstowne
Let’s take a look at the cost of window installation and the kinds of services you may need for your home.
How Much Do New Windows Cost?
On average, Kingstowne homeowners can expect their window replacements to range from $250 to $1,200. The most common installations sit at about $600. This is because window installations are based on several factors specific to your home, including the size, material and number of windows you need to replace, as well as where your property is located.
With windows, efficiency is the most important factor for most homeowners. High efficiency windows may cost more upfront, but by increasing the efficiency of your home — particularly during the summer and winter — they can provide many years of energy savings. According to Energy Star, buying certified energy-efficient windows can save Kingstowne homeowners $359+ per year after replacing single-pane windows.
We recommend requesting free quotes from several window installers to find the right windows and the company that works best for you.
What Services do Window Installers Offer?
The first step of a replacement is to clarify whether you need a full-frame or pocket installation.
Full-frame installations require replacing the whole window — the sill, frame, trim and all. These are most common when you want to change the style of your window or when it has significant damage. Full-frame installations are more time-consuming and will increase overall costs. Pocket installations (or retrofits) entail installing a new window within the existing frame, which makes pocket installations less labor-intensive and costly. But, if the frame has any rot or deterioration, you should opt for a full-frame installation instead.
Your window installation company will be able to advise you on the best type for your project. In Kingstowne, the choice will mostly be influenced by the efficiency of your home and how old your existing frames are.

How We Choose the Best Window Installers in Kingstowne
The EcoWatch Reviews team is different from other reviewers since we assess these companies through a sustainability lens. We’ve assessed the best window replacement companies in Kingstowne mostly based on their energy efficient offerings, as it’s what’s best for the environment and for you as a homeowner. Energy-efficient windows can reduce your energy bills by hundreds of dollars. Along with energy efficiency, our rating methodology takes the following factors into consideration:
Service Area
This one is self-explanatory, but we’ve chosen to highlight window installers that serve Kingstowne so you can find a quality window installation company near you.
Work Quality
We’re willing to bet that you’re not looking for a company to do a shoddy job installing windows. We’ve vetted each installer included in our guide to ensure its technicians are well-qualified and that the company has received tons of positive customer feedback to vouch for its service.
Customer Reviews
Customer feedback is another super important review factor. If most customers don’t have positive feedback about their experience with a certain window installation company, you won’t see it featured on EcoWatch.
Cost
Cheaper windows certainly don’t mean better windows, but we know many of our readers try to keep costs as low as possible. When analyzing the prices of providers, we gave higher scores to companies with reasonable prices and accessible financing rather than “cheaper” services.
Warranty
Protecting your investment in new windows is important to many homeowners. For that reason, window installation companies that have lengthy warranties for products, parts and labor rank higher with EcoWatch.
Years of Experience
Last but not least, we like to see companies that have been in the industry for a while. Window installation companies that have more experience earn higher rankings by our standards. We like to see at least ten years of experience.
Kingstowne, VA Window Replacement FAQs
What is the average cost to install new windows?
The national average cost to install a window is around $600 but can range from $200 to $1,200, based on a variety of factors. The price is typically dependent on the size of the window, the location of your property and the type and material of the window. Also, remember that energy-efficient windows may cost more initially but can save you a decent amount of money a year in energy bills.
Which type of window should I get?
Generally, double-pane windows are more efficient than single-pane windows and windows that do not open are more efficient than windows that do. If you want to be sure you’ll get the most energy-efficient windows, look for models with the blue Energy Star certification — they’re certified energy-efficient by the U.S. Department of Energy.
What services do window installation companies do?
Window installers travel to your property to remove your old windows and replace them with new ones. Some providers install products manufactured by other companies, whereas others are both manufacturers and installation companies combined. The installer will also clean up after the installation.
When is the best time of year to replace windows?
Although you can install windows any time of year, warmer weather is generally better for replacing windows. Additionally, it shouldn’t be raining, as rain can make the installation harder.
How long does it usually take to install windows?
Each window takes around 30 minutes to install based on the type of window. However, the window installation can be a two-day job — or more — if you have a lot of windows that must be installed.
